I remember first testing SOAX in 2021. Still a rookie provider, it already looked promising: the proxies rarely failed, offered flexible filtering options, and had decent management tools. Though painfully slow and still unfinished, the overall service was good enough for SOAX to become our Discovery of the Year.
Now, SOAX can no longer be called a newbie. It has significantly improved upon the weaknesses, snatching our Contender of the Year award in 2023. How does SOAX compare with other major providers? And has it grown strong enough to compete with the market leaders: Oxylabs, Bright Data, and Smartproxy?
Let’s find out.
General Information
SOAX is one of the newer residential and mobile proxy providers. It’s a UK-based company established in 2019 and run by an international staff. In early 2023, SOAX introduced US-based ISP proxies, and it also runs a web scraping API under the ScrapeIn brand.
The company started off as a mid-range provider, positioning itself in-between penny-pinching services with limited features like PacketStream and enterprise-facing behemoths, such as Bright Data or Oxylabs. Nowadays, it’s nearing premium providers in terms of price.
SOAX invests a lot into getting your eyeballs. You can find it on most review platforms like TrustPilot, G2, or Capterra, tech websites like Trustpilot, and even Sourceforge! At one point, the provider used questionable growth hack tactics, such as spamming its website with thin Google-oriented pages; but that remains in the past.
The SOAX of today looks solid. It has ethical guidelines, partners up with The World Ethical Data Forum, and runs a podcast covering ethics in data collection. (You can read or watch our interview on ethics with Stepan, SOAX’s CEO.) And while SOAX doesn’t disclose any concrete sources for its proxies, we know that it offers an SDK for developers to monetize their apps, such as free VPNs.
Residential Proxies
Residential proxies are SOAX’s main and most affordable service. It consists of around 5 million monthly addresses from various countries around the world.
Features
A competent package with advanced customization options.
The residential proxies cover most countries in the world. You might have trouble reaching remoter African locations, but the network has grown strong enough to provide an acceptable number of IPs nearly everywhere. You can check their coverage with available ASNs using a map on SOAX’s dashboard.
The targeting and rotation options are very generous. Few providers offer ASN targeting, and when they do, it significantly impacts the price. Furthermore, you can choose to keep an IP until it goes offline, rotate proxies on each connection request, or specify a custom duration. This level of control you get is pretty amazing.
Though advertised as unlimited, the proxies do have some limits, specifically concerning parallel requests. A basic plan gets you 300 ports (IPs you can access at the same time), and you’re advised not to go over 30 concurrent connections on each. Advanced packages increase the number.
SOAX’s residential proxies support HTTP(S) and SOCKS5 protocols. However, you can only use them to access website traffic through ports 80 and 443. So there’s not much difference between the two out of the box. You can get more ports open if your use case adheres to SOAX’s terms of use.
Both user:pass and whitelisted IP authentication are available. But to enable the former, you still have to whitelist an IP address first. Two IP slots are given for free; additional slots can be bought for an extra fee.
Pricing Plans
Middle-of-the-pack prices.
SOAX offers monthly plans based on traffic. Unlike most competitors, it also factors in the number of ports you can access at once. This makes SOAX somewhat limited, but only if you scrape at a very fast pace.
The plans start at $99. For this price, you get 8 GB of data ($12/GB) and 300 ports at your disposal. The largest plan on display offers 2 TBs of data at $3/GB. If you want more data, or more ports, you’ll be asked to talk with SOAX’s staff for a custom quote.
Aside from the public price, you can get small upgrades that are hard to notice until you look, such as more whitelisted IPs. However, foregoing them doesn’t impact the service in any meaningful way.
To put things into context, SOAX costs less than the big fish like Bright Data, but I wouldn’t call these proxies cheap. They stand somewhere in between the middle and the second third of the pricing range.
Performance Benchmarks
Top tier performance.
We last tested SOAX’s residential proxies in March 2023.
We ran 1M requests over 21 days using the unfiltered pool, 500,000 requests over 14 days using the country pools, and 140,000 connection requests over 7 days using the Australian pool. We enriched IP data with the IP2Location database.
| Gateway | Unique IPs | Residential % |
| Random | 620,810 | 96.08% |
| US | 113,231 | 61.51% |
| UK | 59,660 | 99.41% |
| Germany | 118,404 | 97.80% |
| France | 158,845 | 98.28% |
| India | 59,743 | 96.18% |
| Australia | 8,477 | 99.15% |
SOAX’s residential proxy network has grown to be quite large. Throughout the testing period, we received over 50,000 unique IPs in most locations, and over 7,000 unique proxies in Australia. Compared to early 2022 when we previously tested the provider, it’s made significant improvements.
That said, the IP database identified nearly 40% of SOAX’s US proxies as non-residential addresses. This is likely because the provider included ISP proxy servers in its pool, which sometimes have trouble with IP databases.
#2: Infrastructure performance
This benchmark shared the same parameters as the pool test. Our computer was located in Germany. We targeted a global CDN – it pinged a server nearest to the proxy IP and had a response size of several kilobytes.
| Gateway | Avg. success rate | Avg. response time |
| Random | 99.03% | 1.05 s |
| US | 98.29% | 0.95 s |
| UK | 99.53% | 0.55 s |
| Germany | 99.44% | 0.64 s |
| France | 99.55% | 0.55 s |
| India | 98.58% | 1.81 s |
| Australia | 99.30% | 1.65 s |
The results were great. Our connection requests nearly always reached their target, and SOAX’s response time was under one second in all European locations. To give you some context, in early 2022 this same proxy network was several times slower. Now, it has almost caught up to the top residential proxy providers like Oxylabs and Bright Data.

#3: Performance with popular targets
We made ~2,600 connection requests to each target using US-filtered proxies and a non-headless Python scraper. Our computer was located in Germany. Note that your results may differ based on your web scraping setup.
| Website | Avg. success rate | Avg. response time |
| Amazon | 99.06% | 3.76 s |
| 98.15% | 1.88 s | |
| Social Media | 99.55% | 1.67 s |
| Walmart | 99.51% | 2.39 s |
| Total | 99.07% | 2.43 s |
The results were nearly flawless here, as well. We experienced very few connection errors, even when accessing hard targets like Google or the photo-focused social media network. Few other providers were able to match SOAX under the same parameters when we tested them for 2023’s Proxy Market Research.
Mobile Proxies
Mobile proxies are SOAX’s more expensive service for targets that regular residential IPs can’t crack. It’s one of the few peer-to-peer-based mobile proxy networks in the market. SOAX claims to control around 3.5 million monthly IPs.
Features
Generous filtering options.
SOAX has a unified system for its mobile and residential IPs, so they’re identical in terms of features. This means you get the same granular targeting options (including city and ASN), as well as flexible rotation settings.
The number of ports is limited, but it’s hardly an issue for mobile proxies, which are often used in a more reserved fashion compared to other proxy types.
Once again: if you care about the SOCKS5 protocol, note that it has very few ports open by default. It’s a good idea to ask SOAX if it’s possible to enable the ones you need before purchase.
Pricing Plans
Premium rates based on traffic expenditure.
SOAX’s mobile profiles run on a subscription model that automatically renews every month until you cancel it. As it’s a peer-to-peer network, the main criterion is traffic use. SOAX also factors in ports – their number increases as you scale up.
The cheapest mobile plan costs $99, or the same amount as access to SOAX’s residential proxies. However, this will only get you 3 gigabytes of traffic at $33/GB. The largest plan on display for $6,000 decreases the unit price to $15/GB.
In a broader context, SOAX’s pricing is expensive compared to mid-range alternatives like Smartproxy or Rayobyte and even premium providers like Oxylabs. This wasn’t the case a year ago, but multiple competitors have cut prices since.
Performance Benchmarks
A large and well-performing mobile proxy network.
We last tested SOAX’s mobile proxies in March 2023.
#1: Pool size & composition
We ran 280,000 requests over 14 days using the unfiltered pool, 140,000 request over 7 days with the country pools, and 140,000 requests over 7 days using the Australian pool. We enriched IP data with the IP2Location database.
| Gateway | Unique IPs | Mobile % |
| Random | 227,274 | 98.02% |
| US | 39,604 | 99.70% |
| UK | 10,805 | 99.72% |
| Germany | 16,730 | 99.11% |
| France | 21,771 | 98.06% |
| India | 183,771 | 99.91% |
| Australia | 3,096 | 81.07% |
SOAX’s proxy network is large enough for serious work in popular locations. With nearly 40,000 unique IPs in the US, it even managed to beat Bright Data, which could only muster ~8,200 during the same testing period (in March 2023). You’ll have the best experience in Eastern Europe, where SOAX has the largest presence.
#2: Infrastructure performance
This benchmark shared the same parameters as the pool test. Our computer was located in Germany. We targeted a global CDN – it pinged a server nearest to the proxy IP and had a response size of several kilobytes.
| Gateway | Avg. success rate | Avg. response time |
| Random | 98.22% | 1.72 s |
| US | 98.50% | 1.60 s |
| UK | 98.31% | 1.40 s |
| Germany | 98.16% | 1.33 s |
| France | 98.13% | 1.37 s |
| India | 96.98% | 2.33 s |
| Australia | 98.73% | 2.02 s |
SOAX’s mobile proxies had a really high success rate, proving that the provider’s infrastructure works well. Though longer compared to the residential proxies, their response time is also relatively fast in the context of other mobile proxy networks: similar to Bright Data’s and up to 40% slower than Oxylabs’.

The results were nearly flawless, showing that these IPs hadn’t experienced much abuse.
How to Use SOAX
The dashboard delights but the user experience isn’t perfect.
Registration
To register with SOAX, you have to fill in a form with basic information and your use case, then confirm the registration via an email.
SOAX also requires undergoing a KYC check when you buy a plan, which involves sending your photo ID to a third-party service.
Dashboard
SOAX’s dashboard is an elegant control panel that evidently received a lot of love from the creators. The dashboard covers all the basics one could expect: you can authenticate, set up a proxy server, buy a plan, read the help docs, and get support.
The dashboard’s main screen.
We especially liked the Online Check tab. It shows not only now many ASNs are online in each country but also their connection status. That’s not something we encounter often.
The checker shows both coverage and connection quality.
Another thing we need to emphasize is how attentive SOAX is to new users. Multiple tabs in the dashboard have interactive onboarding wizards that guide you through the hoops of getting accustomed with the service. The Intercom-based chat also attempts to settle you in via a drip message campaign, though we’re not sure if we like this part. Flashbacks to misuse from other websites.
The onboarding wizard appears in most pages of the dashboard.
Subscription Management
SOAX offers self-service for its proxy networks – it’s possible to buy a plan by yourself. This doesn’t apply to cryptocurrency payments, which require contacting support.
SOAX’s dashboard includes wallet functionality, so you can top up the account in advance to prevent charging your card multiple times. This is useful when you want to top up your traffic without getting a new plan. Just be aware that this process is manual, so your access can still be suspended if you’re not careful.
The dashboard has a separate tab for viewing your balance, transaction history, and downloading invoices.
Proxy Management
The proxy setup ritual here is pretty elaborate. Even though you can authorize using a username and password, you’ll still have to whitelist an IP address first. Team SOAX argue that this is to protect themselves and their users. We argue that they don’t like resellers. In any case, keep this in mind, even if SOAX mentions a workaround for people with dynamic IPs.
After whitelisting an IP address, you can set up a proxy server. There are two ways to do so: via the Login & Password flow or the IP Whitelist flow. In any case, you’ll have to choose a rotation time, specify the location and/or ISP, and then map them to the ports you have.
For example, with an allowance of 100 ports, we assigned ports 10060-10070 to Spain and 10040-10049 to the UK. Note that IP address settings override Login & Password, and the provider advises against using both at once.
The two ways to set up a proxy server on SOAX.
You can also create a list of proxies and export it into a text file:
There are multiple options to choose from.
Finally, SOAX offers an API. It’s pretty basic and nothing to write home about. Perhaps acknowledging this, the provider has it disabled until you explicitly request access. According to the help docs, the API’s functions are limited to fetching lists of locations and ISPs. So, don’t expect too much from it.
Usage Tracking
One aspect that could be improved is visualization of data use. The provided graph is small and stingy. You can see how much traffic you’ve expended over a given period, but that’s pretty much it. SOAX could learn a thing or two in this regard, even if there’s no need to go all out like providers such as NetNut have.
This is the only graph for data visualization.
Documentation
SOAX has a documentation hub covering various aspects of its service. It includes:
- an FAQ,
- quick-start guide,
- proxy setup instructions,
- billing information,
- API documentation,
- integration tutorials, and
- video guides.
The hub is pretty comprehensive: there are around 40 different integration guides, some of which provide instructions for multiple tools. Documentation is an area where SOAX has improved noticeably since we first tested the provider.
Hands-On Support
You can contact SOAX’s support via live chat, email, phone, or Telegram. The provider also specifies tickets in the SLA but selecting the Support tab in the dashboard simply activates the live chat.
We contacted the support multiple times using the live chat functionality. The replies came quickly (one exception aside, within five minutes) and managed to answer our questions. All in all, SOAX’s support left us with a positive impression, at least during daytime in Europe.
Conclusion
In just a few years, SOAX has grown into a competent proxy provider and a strong competitor to most mid-range and premium services. While not without flaws, it keeps the qualities that made it special, while significantly improving on the weaknesses. At this point, SOAX is a well-rounded option for anyone that needs residential or mobile proxies.
SOAX Alternatives
Smartproxy is the first place to go if SOAX is not an option for you. It offers similar performance, great user experience, proxy-based tools and more features.
Bright Data is one of the biggest player in the premium space. It offers even more features, some powerful proxy management tools, and complete pre-scraped data sets.
Oxylabs is like a premium version of SOAX. It controls a significantly larger IP pool, and you can get specialized APIs that simplify web scraping.
